Embodiment 1
[0037] like figure 1 , 2 As shown, a separate track structure prefabrication and construction method, the separate track structure includes a separate track support groove and a factory prefabricated track system, through the prefabrication of the separate track structure, the separation of the function of the support groove, the track plate, and the track The system is factory made.
[0038] The prefabrication method of the separated track structure is as follows:
[0039] Step 1: Material preparation: Prepare the materials used in the separated track system, including steel rail 4, prefabricated rail support groove 3, under-rail pad 7, polymer casting material 6, Concrete track slab 1, cast-in-place concrete connection layer 2, steel plate 5 and conduit 8 ; The preparation of the material includes:
[0040] 1. Rail blasting, rust and dust removal;
[0041] 2. The prefabricated rail bearing groove is produced by modular flow;
[0042] 3. The backing plate under the rail...
